I had sex on may 4th and may 11th with my boyfriend. Then we broke up and I know this was a BAD decision but I had sex with my "first love" that I had first EVER had sex with. We did it on May 17th . My period comes between the 20th-27th if I Were to get pregnant who would it most likely be by? Because may 15th I started kind of getting period symptoms because when I'm about to start I crave chocolate and junk food and break out and my boobs get fragile. And another question IF I had sex the 17th with my ex could I still get pregnant 3 days before my period. I know it takes the sperm up to SEVEN days to reach the egg but lets say I don't have sex this month and don't start my period next month does that mean its by him? Or once I start my period there's no chance of pregnancy between either of them because I started my period and your period flushes everything out right? Please help me with answers.
